"[She] sabotaged business dealings and said things behind my back that really upset me," Laurita alleged.

"She wanted us to help make Melissa look bad on camera. It got ugly. Teresa's hatred is very deep."

Laurita, who claimed that she hasn't seen Giudice for almost a year, described her friendship with the Celebrity Apprentice star as "toxic" and insisted that she is not scared of the consequences of speaking out.

"She doesn't intimidate me at all - if she wants to come at me, go for it," she said. "Once the season is over and the reunion is done, her name will not come out of my mouth again."
